Tiberianus

'The original Pervigilium Veneris is thought to date from the fourth century, and is attributed to Tiberianus. Tiberianus wrote a poem, Amnis Ibat, in a similar (not identical) metre, also about the natural world and the "Pleasant Place", although no goddesses appear. Both are unusual in Latin poetry in having a metrical stress pattern rather than the usual quantitative arrangement of long and short syllables.’
